Patent CA-2218620-A1 (CA)
Title: Synthesis of proteins by native chemical ligation
Inventor: DAWSON PHILIP E
IPC: C07K1/04
Filed: 1995-05-04
Abstract: Proteins of moderate size having native peptide backbones are produced by a method of native chemical ligation. Native chemical ligation employs a chemoselective reaction of two unprotected peptide segments to produce a transient thioester-linked intermediate. The transient thioester-linked intermediate then spontaneously undergoes a rearrangement to provide the full length ligation product having a native peptide bond at the ligation site. Full length ligation products are chemically identical to proteins produced by cell free synthesis. Full length ligation products may be refolded and/or oxidized, as allowed, to form native disulfide-containing protein molecules. The technique of native chemical ligation is employable for chemically synthesizing full length proteins.

Title: Information processing apparatus and information processing method
Inventor: SUZUOKI MASAKAZU
IPC: G06T1/20
Filed: 1998-03-26
Abstract: In an information processing apparatus, priorities are assigned to a plurality of central processing units (CPUs) and the CPUs transfer their respective display lists of drawing instructions to a drawing unit on a priority basis.  With such a scheme, when a master CPU (Geometry Subsystem 0) is creating a display list (List #0-1) and a drawing unit (a rendering system) is in an idle state, a right to make an access to the drawing unit is handed over to a slave CPU (Geometry Subsystem 1), enabling the slave CPU to supply a display list (List 1-1) created thereby, if any, to the drawing unit. Receiving the display list (List #1-1), the drawing unit starts drawing processing in accordance with List #1-1.  As the master CPU completes the creation of the display list (List #0-1), the slave CPU returns the right to make an access to the drawing unit to the master CPU, enabling the master CPU to supply List #0-1 to the drawing unit.  Receiving the display list (List #0-1), the drawing unit starts drawing processing in accordance with List #0-1.  Thereafter, when the master CPU is creating a display list and the drawing unit is in an idle state, a right to make an access to the drawing unit is handed over to the slave CPU (Geometry Subsystem 1), enabling the slave CPU to supply another display list created thereby, if any, to the drawing unit in the same way.
